COMPANY, A CORPORATION OF PENNSYL- TOASTER BASE AND FOOT.

Application filed. April 6,

To all whom it may concern:

Be it known that I, CHRISTIAN AALBonG, a citizen of the United States,and a resident of Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement in ToasterBases and Feet, of which the following is a specification.

My invention relates to electric table cooking devices and particularlyto bases therefor.

The object of my invention is-to provide a relatively simple,inexpensive and easily constructed base for an electric table cookingdevice.

In practicing my invention, 1 provide a base formed from a piece ofrelatively thin sheet metal comprising a top portion and a plurality ofintegral depending flanges. The end portions of the flanges areangularly disposed relatively thereto and adjacent end portions arelocated in opposing spaced relation in the same plane. Each end portionis provided with an inwardly extending integral lug, of arcuatecrosssection, each adjacent pair of lugs providing a substantiallycircular opening between said flange ends.

A perforated metal plate, slightly thicker than the lugs, is locatedadjacent to the inner surfaces of the end portions and surrounds thelugs to interlock therewith. A relatively thin base-supporting member,of a suitable heat-insulating material, rests against the inner surfaceof the perforated plate, extending a short distance below the edge ofthe flanges, and is held in place by 1 a bolt or rivet passing throughthe circular opening between the end portions of the base flanges.

In the single sheet of drawings,

Figure 1 is a partial view, in end elevation, of an electric toastercomprising the device embodying my invention,

Fig. 2 is a fragmentary view, in perspective, of a base comprising thedevice embodying my invention,

Fig. 3 is a sectional view through a portion of the'base taken on theline III-IIT of Fig. 2,

Fig. 4 is a view, in side elevation, of an end portion, and

Fig. 5 is a view, in front elevation, of the part illustrated in Fig.4:.

An electric toaster 11, only a portion of 1923. Serial No. 630,289.

which is illustrated, comprises a base 12, a pair of side frameslS, anda plurality of trays 14 supported by the side frames 13 and having aturningmovement relatively thereto. A knob 15 is provided at each sideof the trays 14, (only one of which is illustrated in the drawings) topermit of the operator actuating the tray during the toasting operation.

This application is closely related to the application of Ora A. Colby,Serial No.

630,271, filed April 6, 1923, and assigned to the lVestinghouse Electric& Manufacturing Company, to which application further reference may behad for details of construction of the side frames, of the trays and ofother parts of the device. While I have elected to illustrate myinvention as embodied in a toaster, its use is not limited thereto as itmay be used with any similar devic requiring a base such as is embodiedin my invention.

The base 12 comprises a flat top portion 16 and a plurality of integraldepending flanges 17 that are angularly disposed relatively to the topportion 16. Each of the flanges 17, of which any number may be provided,but as here illustrated, are four in number, are provided with endportions 18 that extend angularly relatively to the flanges 17 and arelocated in substantially the same plane relatively to each other. Eachof the end portions is substantially triangular in contour and theopposing edges thereof extend to within a short distance of each other.

Each of the end portions 18 is provided with an inwardly-extending,integral lug 19 of substantially arcuate cross-section. The lugs 19 areeach substantially 180 in angular extent and may be formed by punchingout a small portion of the sheet metal comprising the end portions 18.The two lugs 19 co-operate in pairs to form a substantially circularopening 21 extending laterally through and between the opposing endportions 18 at each corner of the base 12.

A relatively thin sheet metal strip 22 of substantially triangularcontour and provided with an opening of sufficient size to fit closelyaround the peripheral surface of the two lugs 19 is located immediatelyadjacent to the inner surfaces of the end portions 18, The thickness ofthe metal memher 22 is slightly greater than that of the lateral extentof the lugs 19, and the member 22 interlocks with the lugs 19 to preventany separation. of the end portions 18 from each other.

A foot or supporting member 23 is provided for each corner of the base12 and comprises a relatively thin piece of a suitable heat-insulatingmaterial, the outer surface of which operatively engages the innersurface of the member 22, a clamping means, such as a rivet 24 beingprovided and extending through the opening 21 to hold the twoendportions 19 and the members 22 and 23 in close operative engagement. Themember 23' extends a short distance below the bottom edge, of the endportions 18 in order to raise the base above the surface upon which thedevice may be placed.

The device embodying my invention is one which may be formed relativelyeasily by arel'ati'vely few punching and forming operations and is onethat permits of cleaning and polishing the entire outer surface of thebase and of the same without difficulty" as substantially all of thesurfaces are plane.

Various modifications and changes may be made in the device withoutdeparting from the spirit and scope of my invention, and I desire,therefore, that only such limitations shall be placed thereon as areindicated in the appended claims or are imposed by the prior art.

I claim as my invention:

1. A base comprising a metal sheet having integral depending flanges,the end portions of said flanges being angularly disposed relativelythereto and having integral laterall-y-extending arcuate portions andmeans operatively engaging said arcuate portions for holding saidflanges. in proper operative position.

2. A sheet metal base comprising depending flanges, laterallyextendinglugs, of arcuate cross-section, on said flanges, and means co-operatingwith pairs of said lugs to interlock the same and maintain said flangesin proper operative position.

3. A sheet metal base having integral depending flanges, integral endportions on said flanges extending angularly therefrom in opposed spacedrelation, an. integral latera-llyextendin 4 lug on each of said, endportions, a per erated member surrounding said lugs, and means forholding said perforated member in its proper operative position.

4. A sheet metal base having integral depending flanges, integral endportions on said flanges extending angularly therefrom in. opposedspaced relation an integral, laterally-extending lug, of arcuatesection, on each of said end portions, a perforated, relatively thin,member operativcly engaging one surface of said end portions andsurrounding said lugs to interlock the same, a base-supporting memberhaving one surface operativel-y engaging one surface of said-perforatedmember and means for holding said end portions, perforated member andbase-supporting member in proper operative positions.

5. A sheet metal base comprising a plurality of flanges, integral,laterally-extend ing lugs, of arcuate cross-section, on said flanges atthe ends thereof, a relatively thin perforated member surrounding twoadjacent opposed lugs, and means extending between said lugs and throughsaid perforated member to maintain the ends of said flanges in properoperatively alined positions.

61 A sheet metal base comprising a plurality of flanges, integral,laterally-extending lugs, of arcuate cross-section, on said flanges atthe ends thereof, a relatively thin, perforated member surrounding twoadjacent opposed lugs to interlock therewith, a base-supporting memberlocated adjacent to said perforated member and extending beyond saidflanges, and means for holding said flanges, perforated member, andbasesupporting member in close operative engagemen-t;

7. A sheet metal base comprising a top portion and a plurality ofintegral flanges, integral, lugs of arcuate cross-section, on saidflanges at the ends thereof, pairs of said l ugs co-operating to providesubstantial'ly circular openings between said flange ends, and meansextending around said lugs and through said openings to maintain saidflanges in proper operative position relatively to each other and tosaid top portion.

In testimony whereof, I have hereunto subscribed my name this 26th dayof March, 19.23.
